The invention discloses a vehicle torque control method and device and a computer storage medium. The vehicle torque control method comprises the steps that the friction coefficient of a vehicle running road surface is obtained; the average torque within the preset time after the vehicle runs in the steady state is obtained; obtaining a correction coefficient according to the average torque; and according to the average torque and the correction coefficient, calculating an initial torque for driving the anti-skid system. According to the vehicle torque control method and device and the computer storage medium, firstly, the average torque within the preset time after the vehicle runs stably is obtained, then the correction coefficient is obtained according to the average torque, and finally the initial torque for driving the anti-skid system is calculated according to the average torque and the correction coefficient. The torque reduction amount of the driving anti-skid system at the activation moment is close to the optimal state, the wheel speed can be rapidly controlled, the overall torque level is also guaranteed, and the stability, acceleration performance and climbing performance of a vehicle are guaranteed.

    本发明公开了一种车辆扭矩控制方法、装置及计算机存储介质,所述车辆扭矩控制方法包括:获取车辆行驶路面的摩擦系数;获取所述车辆稳态行驶后预设时间内的平均扭矩;根据所述平均扭矩获取修正系数;根据所述平均扭矩以及所述修正系数,计算驱动防滑系统的初始扭矩。本发明提供的一种车辆扭矩控制方法、装置及计算机存储介质,首先获取车辆稳态行驶后预设时间内的平均扭矩,然后根据平均扭矩获取修正系数,最后根据平均扭矩以及修正系数计算驱动防滑系统的初始扭矩,使得驱动防滑系统激活时刻的降扭量接近最优状态,除了能快速控制轮速之外,也保证了整体的扭矩水平,即保证了车辆的稳定性、加速性和爬坡性。
